Custom websites, AI First.

What struck me about Mathieu is his professionalism and his responsiveness. He supported us at every step and adjusted as our feedback came in, with real flexibility. Rather than a generic demo, he showed real creativity: a fully custom demo that mirrors how we talk with buyers. And instead of a CMS, he gave us access to the code. We update the content ourselves, straight from the Claude app. A real time-saver, and I’m grateful he trained us on the method. A clear website, optimized for search, and full control over our content. The result is beyond my expectations.

Founder, Osmosia

At Renardo Tech, we design electromagnetic field imaging sensors to diagnose power networks and metal structures. A specialized subject we had to make clear and engaging without losing the rigor, all before our upcoming trade shows. Mathieu started with our identity, built from the ground up, then a site that truly carries it: visual codes shaped for us, zero recycled template, a structure built for our field. What struck me was the responsiveness. Site live in under two weeks. Result: we showed up at the shows with a site that stands out. It genuinely builds our credibility, reassures our partners, and today we share our site with pride.

Before, my site wasn’t converting. Today, I share it with partners and prospects without hesitation. Mathieu delivered a real showcase: a custom page for my equipment, a gallery of past projects, Calendly booking built in. Clients land, see my work, pick their slot. Result: more appointments, more signed clients.

Mathieu pulls off complex, creative work where others would have stopped. He delivered a custom site true to our visual identity: clean design, a smooth user experience, fast and responsive on mobile. Then he trained us to run it ourselves: we update the content whenever we want. He also built in search from day one, ready to be found on Google and recommended by AI. The result: we’re fully operational, and we share our site with pride.

Founder, Padel Day

I build a reservation confirmation solution for the restaurant industry, and I needed a reliable tool to automate the whole process without losing hours to manual work. TeneX Studio built me an internal web app fitted exactly to my need: SMS automation through an API, a dashboard per venue, centralized data management. Mathieu has this ability to take a business idea and turn it quickly into a concrete tool you can use day to day. Result for the teams: time saved on operations, and a solid base to grow the business.

Days before launch, my site wasn’t ready, my questionnaire wasn’t finalized. Mathieu stepped in on short notice, in a single day: site finished, questionnaire delivered, live straight after. Result: deadline met, launch saved.
